30733:M 09 Dec 14:45:30.879 # You requested maxclients of 10000 requiring at least 10032 max file descriptors.
30733:M 09 Dec 14:45:30.879 # Server can 't set maximum open files to 10032 because of OS error: Operation not permitted.
30733:M 09 Dec 14:45:30.879 # Current maximum open files is 4096. maxclients has been reduced to 4064 to compensate for low ulimit. If you need higher maxclients increase ' ulimit -n '.

30733:M 09 Dec 14:45:30.901 # WARNING overcommit_memory is set to 0! Background save may fail under low memory condition. To fix this issue add ' vm.overcommit_memory = 1 ' to /etc/sysctl.conf and then reboot or run the command ' sysctl vm.overcommit_memory=1 ' for this to take effect.
30733:M 09 Dec 14:45:30.901 # WARNING you have Transparent Huge Pages (THP) support enabled in your kernel. This will create latency and memory usage issues with Redis. To fix this issue run the command ' echo never > /sys/kernel/mm/transparent_hugepage/enabled' as root, and add it to your /etc/rc. local in order to retain the setting after a reboot. Redis must be restarted after THP is disabled.
